SlLl'PEURTING MECHANISM FOR Siiecification of Letters Patent.

I Patented liilay (i, 1919.

dpblication filed February 13, 1918. Serial IT0.'216,9l1.

To all 10 how it 'mhg concern;

Be it known that l, URMAH R. MITCHELL, a citizen Of the United States, and resident of Uni? Park, in the county of Cook and State of Illinois, have invented certain new l Improvements in. Supporting for Brakes, of which the fola s' 'iecification.

aniein for brslre ()he of the objects of this invention is to adjustably simport brake beams in an improved manner whereby the same may be leveled in accordance with operating conditions.

Another obiect is to provide a simple and effective leveling device for brake beams adapted to meet the various requirements for we idol commercial operation.

Generally wealriiog, these and other objects are accomplished by providing, incombination, a brake beam, :1 safety her there for, a member operatively connected with the safety bar and beam for supporting the latter, and serrated means whereby said member may be adjusted for leveling the brake beam.

The invention is illustrated on the accompanying sheet of dravvingsfln which Figure 1 is a fragmentary side elevation of a railway car truck embodying my invention;

Fig. is a fragmentary enlarged. side ele-- 'vation, parts being in sectiom of my improved leveling device and its associated. parts;

Fig. 3 a sectional view taken plane of? line 3---3 of Fig 2;

.Fig. .l is an ei'ilarged side elevation, parts being in section, oi a modification of the arrangement showi Fig. is a s .onal view taken in; the plane of line 5 jg. 4-.

'llie vai...o:.is now-l feathe of my invention will n apparent mm the following desciiplimi and drawings and will be particu larly pointed out in the appended claims.

l have discl sed my invention in connection with a ran. car truck, including it springplank 10, to which are secured hangin. the

ere ll for supporting a horizontally arranged safety bar 155, the outer ends of which underlie brake beams 13 for preventing the letter from accidentally falling to the tracks in "the event that they become dctaohed from ventioii. elates to so) )ortin mech-' v in Figs. 1 and 2: and,

their normal hangings. In order to prevent the tenslon rods 14 of the brake beams from saggmg, I have provided members 15, preferably of resilient material, which prefer ably are in the form of a loop having one end 16 thereof slipped over the safety bar, While the other end 17 is adjustably connected with respect totlie safety bar. .An intermediate inclined portion 18 of the leveling member 15 slidably receives the tension member 14: of the brake beam, or, if desired, a head 19- mounted on the tension member may slide on the intermediate por tion 18 of the leveling member 15. The end of the leveling member 15 is secured to the safety'bar and the safety bar.secured in place with respect, to the hangers 11 by. spring clips 20, which are secured to the sides of the safety bar adjacent the hang-' ers 11.

In order to adjust the bake beam for proper leveling thereof, 1 have shown, reference being had to Figs; 1 and 2, one portion 17 ofthe resilient leveling device 15 a with serrations or teeth 21, which cooberate the pin 2% and adjusting the member 15 In the desired direction, whereupon the teeth 22 of the. band 23 may be brought intolock-v ing-association with the teeth or serrations 21 of the member 15, and the band again secured to the safety bar by means of the pin 2%. In this Way it is a simple matter to adjust the leveling device for leveling the brakebea-m, and at the same time when the locking band 23 is once set in position, the

parts are positively locked.

referring to Fig. d, it will be noted that I have shown a modification oi? my invention wherein the outer end of the safety bar Edie provided with teeth or serrations 27, which cooperate with the teeth or serrations 28 on the inside edge of the down- Wardly extending portion 29 of the spring leveling member '30, thebrake tension men 1,3,0

her 31 being slidably supported upon the in clined portion 32 of the lmeling member it It Will be noted also that the leveling memher has but the single end 29 engaging with the safety bar :26. The band 33 which embraces the serrated end 25) of the leveling member 30 in this case is not serrated, the function of the band 33 in this case being merely to hold the serrated portions of the leveling member 30 and of the bar in normal locking position, and for permitting their release when it is desired to adjust the vertical position of the beam.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claim:

l ln combination, a brake beam. a safety member therefor, a member operatively eonnected With the safety member and beam for supporting the latter, and serrated means whereby said member may be adjusted for leveling the brake beam.

2. In combination, a brake beam, a safety bar therefor, a toothed leveling member eonneeted to the safety bar and operatirely connected to the beam for slidably supporting the latter and cooperating means whereby the leveling member may be adjusted and locked in adjusted position.

3. In combination. a brake beam, a safety member underlying the same, a support for the beam, and a cooperating toothed mem her for releasably locking said support; to the safety member.

t. In eombimition, a brake beam, a safety bar underlying the same, a support for the beam, and a cooperating toothed member for adjustably and releasably locking said support: to the safety bar.

5. In combination. a brake beam, a safety bar underlying the same, a member for slidably supporting said beam, said member havin a toothed portion, and a member embraeing said toothed member and bar for seeuring the same together.

ti. lu ((Jlllbitliltitfll, a brake beam, a safety bar therefor, a member for slidably supporting the brake beam and having a toothed portion, and a toothed member associated with the toothed portion of said supporting member operatively connected to the safety bar for holding the supporting member in adjusted position.
